Why use Multicheck eco A II?

Multicheck eco A II is a computer-assisted, automated test bench that makes it easy to carry out all of the static and dynamic low-pressure, medium-pressure and high-pressure tests that need to be performed on full-face masks, lung-governed demand valves and SCBAs.

The fact that this test bench operates largely automatically not only guarantees that the highest standards are met in terms of equipment testing but also makes for utmost user-friendliness. During equipment testing, the feature-packed MENZL Equipment Management and Testing program automatically controls the required test procedures and pressure levels as well as the artificial lung, and records data in the same reliable and tamper-proof manner that all MENZL software products are renowned for.

With a view to reducing dead space and maximizing accuracy, lung-governed demand valves are connected to a  dedicated port for static tests rather than to a mask or the dummy head. Chemical protective suits (CPS) and CPS exhalation valves can be tested using accessories (sold separately).

A variety of optional extras and upgrades such as a keyboard tray, a built-in second-load simulator or a CPS filling unit make it possible to expand the capabilities of the test bench to meet individual needs and requirements. Multicheck eco A II can also be (retro-)fitted with a pneumatic tightener for masks with five-point head harnesses.
